(This component must be used after generating the mesh.) **Input**: D: Enter the area of a load. You can input points, lines, surfaces or closed soilds. Ux: The displacement in the X-axis direction. If you don't input any vaule, there will be no constrains in this direction. If you input 0, there will be constrained in this direction. If you input a non-zero value, this value will mean displacement in this direction. Uy: The displacement in the Y-axis direction. If you don't input any vaule, there will be no constrains in this direction. If you input 0, there will be constrained in this direction. If you input a non-zero value, this value will mean displacement in this direction. Uz: The displacement in the Z-axis direction. If you don't input any vaule, there will be no constrains in this direction. If you input 0, there will be constrained in this direction. If you input a non-zero value, this value will mean displacement in this direction. Tol: The tolerance for area determination. This parameter will be invalid when you input closed soilds. **Output**: Supports: Output a support.
